Patent attributes
A device is disclosed for pre-tensioning an occupant restraint harness coupled to a seat portion of a motor vehicle seat and/or for pulling down the seat portion of the vehicle seat toward a seat base in embodiments in which the seat portion is suspended above the seat base. An elongated housing is secured to the seat portion, a web is coupled between the restraint harness or seat portion and the seat base or a support structure to which the seat base is mounted, and a piston carried by the housing defines a web guide in contact with the web between its two ends. As the piston moves along and relative to the housing in response to actuation thereof, the web guide displaces the web within the housing to pre-tension the occupant restraint harness and/or to pull the seat portion toward the seat base.
